矸石充填
waste filling
- 根据充填体的压实原理、岩层力学及相关理论， 推导了不同矸石充填体 压实度所对应的压缩值及等价采高的解析式；
The compression value and the equivalent mining height for different compactness is obtained based on compaction principle of gangue backfills and rock mechanics. - 同时冒落的矸石充填采空区，对基本顶和覆岩具有一定的支撑作用，故该煤柱是长期稳定的。
Meanwhile, the goaf is filled by the falling gangue, which can certainly play a role in supporting the roof and overlying strata, so the strip pillar can keep stable for a long time. - 经过模拟计算和实践证明：利用破碎矸石充填留巷能够确保留巷系统的稳定性；
The simulation calculation and practices showed that the goaf side gateway backfilled with rushed falling rocks could keep the stability of the goaf side gateway system.
